← GeographyWhich consequence results when caldera-forming eruption generates pyroclastic surge?
A)Widespread landscape thermal sterilization occurs✓
B)Stable isotope fractionation gets disrupted
C)Localized regions experience increased albedo
D)Atmospheric aerosol optical depth decreases
💡 Explanation
Landscape thermal sterilization occurs during a pyroclastic surge because high-temperature gases cause flash heating, rather than changes in albedo, isotopic composition, or transient optical depth changes; therefore, widespread destruction effects result.
